He is not talking about what you think of as a TB. Ford offered something called CFI which is similar to the TBI chevy used before multi port fuel injection. I would think it is close if not the same, if all else fails they are cheap to pick up.
I am talking about a Fox. The CFI was offered on Mustangs in 84-85. So my guess is it is a 84 or 85, just a logical guess off of what the OP has mentioned.
